RSS Feed not valid after update

Hi,

I had updated my template to the latest version and i observed recently that the posts were not published in facebook page through RSS Graffiti. At first i thought its a problem of the RSS Graffiti service and i switched to twitterfeed. When i try to register my feeds i get: Your feed might be empty or missing publish dates or GUIDs. A feed needs to contain publish dates or GUIDs in order to work with twitterfeed. I have erros through other services as well.

Any solution?

The website is: www.profilnet.gr
and an example of a feed is http://www.profilnet.gr/index.php/eidiseis?format=feed

Through feed validator i get the erros on line 1
